The given line graph indicates the proportion of income which people in the US and the UK spend on petrol.
Overall, it is obvious that the gap between the poorest and the richest in the UK outweighs that in the USA. Conversely, the figures for the middle-income in both regions have a similar trend.
It is noticeable that the percentage of income that the poorest in the US spend on fuel can be fourfold that paid by the poor in the United Kingdom, with around 4% and 0.5% respectively, suggesting that the poor in the UK do not use cars very much. In the USA, the proportion of income spent by the poor reaches a peak of nearly 5.5%, then falls gradually. In contrast, in the UK, there is a steep increase by 2% falling into this category.
The data for the riches in both countries witnesses a contrasting movement with an upward trend in the United Kingdom, whereas the United States undergoes a downward trend. On the other hand, the statistics for petrol spending of the middle-income in 2 distinct nations namely the US and the UK have equivalent figures in rising and falling.
